It’s always a tough choice between wide angle and not so wide angle lenses. Wide angle lenses are very good to capture the entire scene, but you are going to lose some details since you are cramming more viewing angles into the same size image sensor. It also means you need to deal with losing sharpness around the corners. Sure! there will always be an ultimate lens does it all! But my limited depth of pocket probably just isn’t going to cut it. Unless someone sponsor me of course 🙂
Anyway! Back to the topic..
These tests are trying to find the balance of color and sharpness on both lenses. I have to say Pentax came a long way to make DA line-up appealing. Lens construction fits the bill, image sharpness and color rendering are not bad either! Although I prefer FA series for the manual focus handling and sharpness, but You can see the color differences between them.
Sony A7 + Pentax 21mm Limited (Cropped to 25mm on Full Frame) + Capture One Pro 7
Late winter, early spring is finally here in Seattle. I intended to test how much my Pentax 21mm is actually providing me. First of all! I understand why the reason Ricoh/Pentax likes to keep themselves in the APS-C market. However, I hate to admit! I really miss a lot of nice Pentax lenses that provides full frame coverage.
IMHO, APS-C lenses are designed to be only use on APS-C cameras. I wouldn’t expect much more than APS-C crop size. I found out the cropping factors I like the most from shooting an APS-C lens like Pentax DA 21mm Limited to be 25.6mm on a Full Frame instead of using it as 21mm on APS-C (31.5mm on a Full Frame).
Here are some handheld shots I walk through University Village nearby University of Washington the other night.
Over years! I’ve been searching for compact design to carry out. I am currently moved away from full size DSLR, large zoom lenses, and backpack size of camera bags. While I am moving towards to compact, or mirrorless mid-pro cameras, my photography narrowed down to prime lenses only.
Prime lenses are great! They are tiny, light weight, yet pockable. However, that also means I can’t always put them in the pocket and if I place them into my HUGE camera backpack, they will shift around hitting sidewalls inside the backpack.
Pentax DA 35mm AL F2.4 believed to be the same optical formula from the legendary Pentax FA 35mm F2.0. The only difference is that Pentax made this lens as a DA version (APS-C lens).
While Pentax is trying to attract new users by producing cost down plastic lenses while keep up the performance of this lens, it brings happiness to loyal customers as well. DA35 produce outstanding images! It has very short minimum focus distance. It has wonderful bokeh and unbelievable sharpness at wide open aperture (F2.4). Since it’s made from plastic, it’s very light weight to travel with.
Fuji GA645zi is probably one of the most advanced medium format autofocus rangefinder (RF) at 90s. Although the compact size does shines through most of the medium format cameras, it also has it’s downsides.
Lens is sharp at it’s best. After all, the maximum aperture was quite slow. on the second thought! Even the famous EBC doesn’t help much on the flares. It’s best as it is, a “Point and Shoot” Medium Format Autofocus Camera. Even the autofocus is sometimes hit and misses with it’s autofocus confirmation. You simply can not be sure where the camera is actually focusing at! 😦
